Hi agentwhy,
Thje choice between a box spring and frame or a platform bed would be a personal preference (they could both work fine).
The foundation thread here has much more information and some good options listed.
Yes. Dunlop latex is a denser material and has a different feel from talalay. It is denser, less “springy”, and has a higher compression modulus (gets firmer faster) than Talalay in an equivalent ILD (softness/firmness level). There is more information in this article about the differences between them. They are both high quality and comparable value materials … just different in feel and performance. The other difference in the mattress is that it has a more expensive and higher quality bamboo/wool quilted cover which would have better temperature regulation and humidity control.
